Circuit (Network) analysis is the process of finding the voltages across, and the currents through, every component in the network. Consider using in conjunction with tags for the particular analysis technique(s) in question: "nodal-analysis", "mesh-analysis", "superposition", etc.

Is this equation in the photodiode model wrong?
Check the PULSE command in your simulation. The duration (width) of the current pulse is probably too short, only 0.2ns (ignoring rise and fall times). Did you mean 0.2us (microseconds rather than n …

Multiple voltage source problem from Boylestead
The values for Va & Vb you stated are correct for the diagram you drew. If the book does not agree then either the book is incorrect, or you have misstated the question.
Perhaps V2 is not a voltage s …

How do we measure inductance with a DC source?
My interviewer said: The voltage peaks at times t1 and t2 won't be a function of the inductance, but based on “the nature of how you're testing it”. His view was to ignore those peaks and focus on th …

Need help understanding transient inductive networks
When the circuit is in the storage phase is R2 shorted?
No.
If it was being shorted, then it would cause infinite current to flow from E.
Perhaps the confusion is that the inductor, L, can be consid …

Contradiction between two circuit simulators in measuring open loop gain
I suspect the difference is due to the BJT models being slightly different between TINA and LTspice. The parameter values to compare would be those that determine the following static (DC) transfer f …

Do you know about topologies that look like this?
Do you know about topologies that look like this?
Yes.
Is this right?
Yes, that is one variant of the family of converters known as "3-level boost converters".
How do I search it?
Well, there ar …

Constant volatge at the output of LM311
Check your R6 (or is it R5, your schematic is hard to read?), is it really 1kΩ, or is it perhaps 100Ω? The output voltage of 0.8V is more in line with R5 being 100Ω, not 1kΩ. However, even if R5 is …

How can I analyse this circuit to get a function for Vs in terms of Vin?
If all the voltage at all nodes in the circuit stay within acceptable bounds, say, +12V and 0V, then you could have one power supply to feed both the power circuit (that supplied current to the load) …

What happens if I feed a diode (in the forward direction) from a DC current source?
Let's assume you want the current source to split equally between the two branches, ie: 0.5 * Ibias in each branch. The value of R would start at zero, and would need to increase to the point where t …

Why does a class A amplifier stop amplifying at high frequencies?
Mainly because of the Miller effect.
Within the MOSFET symbol on your schematic, there is an ideal MOSFET surrounded by other components, known as parasitics (or non-idealities) that cause the behavio …
